SIP2SIM and SMS

Overview

Sending SMS from the handset can work in these ways:

• Without any configuration, outgoing SMS from the handset/SIM will have the originator as: sip2sim.
• With configuration, we can post the data to a URL of yours - you can then process this and relay it on how you like
• With configuration and a Number from AAISP, we can handle the SMS for you.

Receiving an SMS on the SIM is done in 1 of 2 ways:

• With a Number from AAISP we will send incoming SMSs to the SIM (see below for more info and restrictions)
• You can send a SMS by calling a URL. i.e., you can integrate this with your own systems/PBXs.

SMS with an AAISP Number

If you have a VoIP number from AAISP that supports SMS (see VoIP - SMS for a list) then SMSs can be sent to and from the SIM. This will need 2 settings on the Control Pages to be set:

1. Set the 'MO SMS URL' field on the Control Page for the SIM to be the VoIP number (+44 format)
2. Set the 'SMS Inbound' field on the Control Page for the VoIP number to be the ICCID

On the SIM, set the 'MO SMS URL' to be the VoIP number

On the VoIP Number set 'SMS Inbound' the to be the SIM ICCID

Posting a SMS from the handset to your URL

1. Set the 'MO SMS URL' field on the Control Page for the SIM to be the URL to your script.

Sending a SMS to the SIM using Curl

You can send a SMS to the SIM using curl (a command line tool available on most operating systems, and so this can be integrated in to your own systems.

Be sure to enter a 'MT Password'

Example:

curl --silent --get \
--form-string iccid=894453852500xxxxxxx \
--form-string password=secret \
--form-string message="Hello Alex" \
--form-string originator="Office" \
--form-string username=894453852500xxxxxxx  \

SMS message to 894453852500xxxxxxx
OK:1

You can also send via our Send a Text page - Use the following fields: Password, Message, Originator and ICCID fields.

SMS with a non-AAISP Number

If you are using our SIP2SIM service and are not using one of our numbers then SMS is still possible in the following ways:

Outgoing

• Without any configuration, outgoing SMS from the handset/SIM will have the originator as: sip2sim. See the SMS API page for more details.
• A URL can be added to the Control Pages, and we will post the SMS to the URL. e.g., this can then run a script at your side and the message can be handled in any way that you would like. e.g., passed on to a 3rd party SMS provider, run custom scripts etc.

Incoming

Incoming SMS to a number that is not an AAISP one will be up to the company who host your number. They may be able to email it to you, or they may have a way where they can post the message to a URL, in which case it may be able to use our SMS API for the message to be sent on to the SIM. See the example above, and the SMS API page.
